Rare halos

The Sirius halo camera was taken to the lines on Saturday morning 5.3 after a maintenance break, and several halo shapes were found in the images in the first hours.

There were side suns and a faint backdrop in the sky from the morning, but no miracles were found in the stack (Fig. 4). Before eleven, there was already a whirlwind from Kouvola and I took the camera back to work. Diffuse from the ring, from which no shapes could be properly distinguished with the naked eye, was sufficient until 3 p.m. The stacks revealed a decent pie show that remained very similar all the time. Therefore, there is only one stack of 240 images taken every 6 seconds from 10:54 to 11:18 (Figures 1-2). The main image is three times believed and bg-processed, the second image is...

Tero Sipinen, Ursa (Etelä-Suomi)

A whirlwind! EDIT 25.3. Let's finally update: Halon Day started at nine in the morning with a weak tire and a little later sa and pillar. The first pyras at 18 and 9 degree points were subsequently found in the ten images taken. The next time I checked, I was already clearly pyramidal when the tire looked thick and diffuse. By handling, e.g. 35r (Fig. 2, 10.42). Alerts to move and stacks to shoot. I was badly overwhelmed by the departure for the trip, but luckily I took a reasonable number of stack photos (64 photos from 10.51-11.15) before leaving. In Figures 3 and 4, a couple of differen...
